While performing some load test on our stage server, it was getting srtuck up at some point of time. When we verified the Integration server log folder, we could see the file “RepoV4Error20090924.log” created with an empty content along with the server log files.
Can any one if you please clarify why it got created? Is there any corruption in repository?
repoV4 is used for storing the process model (and other info), if you think you are not using repoV4, you can can just remove the contents under IntegrationServer/WmRepository4 (backup first), then try to restart IS, see if fix your problem.
